Evaluate: [[x,y,x+y],[y,x+y,x],[x+y,x,y]]

Evaluate det[[x,y,x+yy,x+y,xx+y,x,y]]

Evaluate {:[( x,y , x+y),( y,x+y,x),( x+y,x,y)]:}

The determinant [[x,y,x+y],[y,x+y,x],[x+y,x,y]] is divisible by

Evaluate {:[(1,x,y),( 1,x+y,y),( 1,x,x+y)]:}

Evaluate {:[(1,x,y),( 1,x+y,y),( 1,x,x+y)]:}

Using properties of determinants , find the value of k if |{:(x,y,x+y),(y,x+y,x),(x+y,x,y):}|=k(x^(3)+y^(3)) .

Using properties of determinants, prove the following |[x,x+y,x+2y],[x+2y,x,x+y],[x+y,x+2y,x]|=9y^2(x+y)

Using properties of determinants, prove the following |[x,x+y,x+2y],[x+2y,x,x+y],[x+y,x+2y,x]|=9y^2(x+y)
